craftyrc (5)

NAME

crafty.rc, .craftyrc - run control for crafty(6)

DESCRIPTION

A Crafty run control file should contain a sequence of valid Crafty commands, terminated by the command "exit" to restore standard input to the keyboard. This manual page gives a skeletal example. Even the few commands used are not fully explained, and should be looked up in "crafty.doc". As for where the run control file should be, see crafty(6).

EXAMPLE

# $HOME/.craftyrc (comments like this are fine).

! echo "Reading $HOME/.craftyrc ..."
# Crafty's shell escape "!" lets us at system commands.
# Echoed information will be in "log.001".

# PROCESSOR USAGE:

mt=0
# The "mt" command indicates how many processors to use.
# With zero, multiprocessor support is disabled.
# If Crafty has been compiled without SMP support,
# a harmless error message results.

# MEMORY USAGE:

hash=24M
# Memory allowed for transposition hash table.

hashp=3M
# Memory for pawn structure hash table.
# These commands are well explained in "crafty.doc".
# Hopefully, someone will step in and rewrite this
# example to properly use the more intricate "adaptive".

# ENDGAME TABLEBASES:

egtb !
# Enable tablebases.
# The "!" has Crafty pat us on the head if we happen to
# play a good move in the late endgame.

cache=1M
# Define memory usage for caching tablebase probe info.

# OUTPUT TUNING:

show book
# Make Crafty verbose in the opening.

# FINALLY, RESTORE CRAFTY'S INPUT TO THE KEYBOARD:
exit

# End of $HOME/.craftyrc
